I have an object dependency that is showing up for two tables that used to
have a relationship setup.  But I went in under "Relationships" and deleted
the relationship, but the object dependency is still showing up and there is
a plus sign next to the previously connected field in each of the tables
(when you expand the plus sign, it shows the other corresponding table
info).

What else do I have to do to remove this object dependency if deleting the
relationship doesn't remove it?
